Boston woman turns camera on man who she claims was secretly filming girls

A US woman has confronted a man on the street who she claims was secretly filming underage girls.

Jase Dillan, an aspiring singer from Boston, was walking down Newbury Street in Boston last Thursday afternoon when she claims she saw the man using a camera to film her and two "very obviously" underage girls.

"I could see him zooming in on (women's) crotch areas," she told Cosmopolitan. "He had the camera positioned low. He was zooming in on crotches. When they walked by, he would nonchalantly turn and zoom in on their asses."

After phoning police and watching him for more than 10 minutes, Ms Dillan said she decided to confront the man about his alleged behaviour.

"Am I making you uncomfortable? You don't like being filmed without your permission? Because that's what you were doing," she asks loudly so passers-by can hear.

The unidentified man, who was wearing a wedding ring, first denies knowing what she is talking about, but after being followed eventually asks, "Why do you think I would need your permission?"
